. Show the first eight words of the key expansion for a 1 28-bit key of all zeros in an AES encryption scheme Use the algorithm as shown in the figure given below where the function g is given as follows a. a circular one byte circular left shift on the input word. b. a substitution on each byte of the word using the AES 256 byte S-BOX (this is the same S-box we used in class to find the output of the first round of AES and is posted on CILearn. An EXOR with a Round Constant which for round one is given as (01,00,00,00) hex. c. b) Function g (a) Overall algorithm AES Key Expansion
